REQUIREMENT
Requirement to drive a Trailer Unit from a Tractor
Unit to give a wheel drive on an articulated vehicle.

CHALLENGE
Problem with this type of application is that as the drive is taken over
the hinge point the slip and joint angles have to be high enough to cope.

SOLUTION
We supplied a 45 degree working angled shaft that had slip movement
of 800mm.
These are now running successfully.

REQUIREMENTMine Hunters for US Navy required a driveshaft with the following
features

Non
- magnetic
25000 hours life
to allow axial and lateral movement
To withstand shock loading of a mine explosion and still take the Mine-Hunters
home
To run quietly beyond its operating life

CHALLENGEWhat
non-magnetic material could be used that would give us the strength required
to cope with all of the requirements and acceptable to US Navy?

SOLUTIONAluminium Bronze, Short Coupled Driveshafts were manufactured from
solid forgings. The first Mine-Hunter has now been in service since January
1998 without any problems, the Navy are delighted.

REQUIREMENT
To run a drive shaft through a fireproof wall and retain the integrity
of the enclosure. Operation of the driveshaft to be oil based services
on and offshore.

CHALLENGE
How to keep an airtight seal while allowing the driveshaft to transmit
full power through the wall of the enclosure.

SOLUTIONUtilise
a sealed flange mounted self - aligning bearing on the wall of the enclosure.
This also gives support to the driveshaft. We now have several of these
units operating in the field.
